Wet electrostatic dust separation in ammonium nitrate plants

Alessandro Gullà, AWS Corporation srl, Italy

Fertiliser production plants have many issues to be solved regarding emission levels, mainly relating to dust and ammonia, and which require different types of technical solutions and products.

Options that companies such as AWS can supply to achieve the required emissions limits include

  • demisters, candles, meshpad and lamellar type mist eliminators
  • Jet Venturi scrubbers
  • Wet electrostatic precipitators.

This presentation will review the principles of operation of these technologies, with a comparison between them in terms of efficiency removal and pressure drop.

Focusing on dust control, many industries may be required to reduce the amount of particulates they release into the environment.  These requirements typically depend on application field, location of plants, type and quantity of dust.

The technologies for the dedusting of industrial plants are as follows:

  1. Scrubbers
  2. Filters
  3. ESP
    • Wet ESP
    • Dry ESP

The presentation will review the applications, advantages, and limitations of each of these technologies. It will conclude with a description of a case study: a new installation of WET ESP technology to control dust at an ammonium nitrate plant run by Lovochemie a.s, which is the first time that this technology has been used in the fertiliser industry.

There will be a written paper accompanying this presentation.

Reducing emissions from ammonium nitrate based fertiliser operations

Graeme Cousland, Begg Cousland Envirotec Limited, UK

Process gases from the production of HDAN ammonium nitrate and ammonium nitrate based fertilisers (and explosives grade LDAN) are contaminated to differing degrees by soluble or insoluble solids and ammonia, which then require gas scrubbing or gas filtering equipment installed to prevent emission to atmosphere.

Fibre-bed technology has been used for decades and with Brownian Diffusion type designs prilled ammonium nitrate and ammonia emissions can be minimized. A key requirement for using fibre-bed candle filters is that there are no insoluble elements in the exit air, which would block the filters. Fibre-bed candle filters using P.T.F.E. media can sometimes also be used to treat the vapour from ammonium nitrate neutralisers, capturing A.N. particles and NH3.

Where there are insoluble solids present, for example C.A.N. production and emissions from granulators and dryers, then there are various designs of gas scrubbing equipment that can be implemented, to achieve legally required atmospheric emission limits, while being as maintenance-friendly as possible. To improve operational performance and to minimise down-time and cleaning, optimised packing materials for cross-flow and vertical fume scrubbers, deliver longer life and better results. Solid particles and ammonia fumes can also be handled without risk of blocking using the Begg Cousland ‘Becoflex’ rotary brush technology, which is a highly efficient and low energy package system, that requires significantly less liquid than most other wet scrubbers.

The paper will review and give examples of these issues, solutions and results.

There will be a written paper accompanying this presentation.

This webinar will be worth 1 BASIS FACTS CPD E point and 1 PN point.

Explanation of the new Regulation (EU) 2019/1148 on explosives precursors

Thursday 4 February 2021
13.00 BST / 14.00 CEST

 

Mariano Alessio Vernì of SILC Fertilizzanti Srl, Italy

This webinar, given by Mariano Alessio Vernì of SILC Fertilizzanti Srl, will provide a brief over view of the requirements and implications of this new EU legislation that comes into force on 1 February 2021.

The presentation will cover the differences between the Reg. (CE) 98/2013 and the new one; and the definitions and role of the “economic operators” within the supply chain. Note that these potentially include manufacturers, importers, wholesalers, cooperatives, dealers, distributors, professional end-users and hobby-sector.

The webinar will also cover how to inform the various players within a supply chain; the types of substances and products listed in Annexes I and II (practical examples) of the regulation; the Customer’s Statement (Annex IV); how to manage availability of these products on the market, their possession and their use; post-sale verification and reporting of suspicious transactions, disappearances and thefts to the EU national authorities. It will also highlight practical consequences of this new regulation for the market.

Please note that, in relation to regulatory matters, the IFS and its invited speakers cannot and do not provide advice. This webinar will provide an overview of the regulation, its requirements and implications for the industry in general.

Developments in the production of phosphate fertilisers

New technology to upgrade phosphate sources into Di-Calcium Phosphate  

Alexandre Wavreille, Prayon Technologies, Belgium

Following demographic expansion, the demand for phosphatic nutrients is continuously increasing all over the world. In this context, the quality of the phosphate raw material, conventional or secondary, is slowly decreasing year by year.

Prayon Technologies has developed and patented a new process route using sulphuric acid in dilute conditions that allows production of Di-calcium Phosphate (DCP) from phosphate sources with a low P2O5 content or rich in impurities. This DCP can either be processed as raw material for phosphoric acid production or used in the animal feed field.

There will be a written paper accompanying this presentation.

Use of data analytics to improve process control and efficiency, including prediction of emerging problems

Hadrien Leruth, Prayon Technologies, Belgium 

Any phosphoric acid plant generates data containing useful information to be analysed and interpreted. From this data management and analysis, a decision support system can be developed by introducing new variables called ‘soft sensors’. These provide a real-time indication of the plant performance, its maintenance level, and even the quality of the product.

Based on this concept, Prayon has demonstrated in Belgium the value of implementing such a system to get the best from a phosphoric acid plant. It consists of a dashboard that can be adapted to the needs of any other producer.

There will be a written paper accompanying this presentation.

BASIS FACTS CPD points will be earned.

Prayon Technologies, a world leader in phosphate technology, is pleased to support this webinar.

A review of latest developments in the measurement of pH in ammonium nitrate reaction loops  

Francisca Galindo Paniagua and Gonzalo Fernández Ozalla, Fertiberia S. A., Spain

Control of pH is of extreme importance in the neutralisation reaction process of nitric acid and ammonia to produce ammonium nitrate. Many accidents, including explosions with fatalities, have been reported related to problems in the pH control of ammonia nitrate reactors. The state of the art for this control is a standard pH probe measuring the pH of a sample, usually at 10% of concentration and at a temperature lower than 100oC. The sample needs to be diluted and refrigerated to avoid crystallisation and damage in the pH electrode. Based on the sampling system, the pH measure is delayed, it is quite unreliable and attention-demanding; typical failures of the system are crystallisation of the sample, uncontrolled dilution water, uncontrolled cooling and delays of the response. 

In Fertiberia-Sagunto the pH control of the reaction is of greater importance due to the designed working conditions at high temperature (180oC) and at low pH (close to 1). The original pH control (standard system plus tritrometer) was not safe enough and caused many problems in the pH control system of the reactor. Fertiberia has recently installed a new control system concept based on sensors that measure free nitric acid or ammonia content. They are installed directly in the exit pipe of ammonium nitrate solution from reaction, at high temperature. This system gives an instant response of the excess content of the reactants, without delays and directly translatable to pH. Several months of operation have proved the reliability of this control system and the consistency of the results..
